To all whom it may concern:

Be it known that we, EDWARD B. Hess, of the borough of Brooklyn, city and State of New York, and JOSEPH M. Sro oHToN, of the city of Yonkers, county of Westchester, and State of New York, citizens of the United States of America, have invented certain new and useful Improvements in WVriting-Machines', of which the following is a specification.

This invention relates to' typewriting machines of the, general character-disclosed in U. S. Patent No. 700687 granted May 2Q, 1902 to EdwardB. Hess; and comprises a novel, eflicient and economical construction of the type bar actuating devices.

In the accompanying drawings which show so much only of a typwriting machine as Willserve to illustrate .the nyention, Figure 1, is a vertical tion; Fig. 2, a bottom platen, type bar segment and type bars, and showing the type -bar operating links broken away in front of their points otconnection with thetype-bars; Fig.3, a detail plan. of part of the stepped keyboard plate; and Fig. 4, a vertical transverse section on line 4-, 4 zontal key-board plate.

The main frame is shown, in this instance. as composed of an 0 en rectangular casting (5 provided on the ottom at each side with two cushion-feet a of rubber or other suitable material. A front strike machine is shown, of which 7) is the platen, c the slotted type-bar segment; and 1 typebars, two only being shown. The'type-bars extend from the segment toward the front of the machine, and, as usual, rest normally upon a segmental rest 6.

The construction of the type-bar segmentand pivoting of the bars therein may be of any appropriatecharacter. As showlnd is a pivot rod or wire common to the entire series of type bars. The heel (Z of eachlype bar. below the segment, has connected longitucli dal-fsecplan omitting the to 11 an operating link f which extends under the assemblage of type bars toward the front of the machine and is flexibly connected to the rearend ofa. shorter link ywhose front end is pivotally connected to a fixed piece 71, on the frame.

I In the construction illustrated the joint between the through part of the bottom =liori-' ing u on tie position of the normal links f, g, is made by'means of the, end of the vertical stem 2' of a ush piii finger piece 2" in. the keygboardf' rear end of link f is formed with a hook oineye that engages in an aperture in the such joint permitting, to the required extent, a universal movement. The front end of this link is provided with a snap hook j, by means of which it is engaged with the aperture nearest the end of the stem 5. The

rear end of the front-link g is formed with a hook or eye which engages the upper aperture in the finger piece stem 2', and the front end of this link is formed with. a snap hook j, that engages an aperture in a lug or ear h punched on three sides from the horizontal dott-om plate k of the key-board and turned own t right angles.

heel of-the type-bar,

m is the stepped top plate of the keyboard, there belng four steps for the four series of finger pieces 1, 2, 3, 4, arranged as usual in lines transverse to the machine.

There is, of cour e, for each type-bar a. link f, a link 9, and finger piece and stem. The lugs or cars h are arranged in a alane hori= zontal, or substantially so, in our transverse seriescorrespondin to the transverse rows in the bank of nger pieces. The links f will, of course, varying an les from the horizontal dependeorres )onding type ar in the type, bar segment. he ar rangement vof the 111 s or fixed pieces or anchor points for the front ends of the front links in a horizontal plane, or substantially so, but in separate transverse rows corresponding with the rows of the finger pieces, constitutes one of the leading features of this invention quite irrespective of an particular mode of hinging the pairs of hnks together attheir adjacent ends or of operating the flexlng connections formed by the links. The arrangement is one that permits of a low key-board, and the construction is simple and economical because all of the anchor points may be conveniently and cheaply formed from a single piece of sheetmetal.

posit-ion indicated in Fig. 1 by means of suitably applied springs.

In the present construction each link f hasclamped, or otherwise rigidly attached to it, at a suitable point in front of the heel extend rearwardly ati All of the ,parts may. be held in the 2 c v a 967,915.

'-As seen in Fig. 3,-thc apew t u'res Pin the top plate of the key board for the, passage of the finger piece stems are formed with lateral enlargeni'ents tto permit the passage of lateral pins'z' oil the stems,

*which constitute stops acting against thebottom of the bottom 'platelr; to limit the upward movement ofthe stems. The slots in thisbottojm plate lc, through which the Q stems of the finger, pieces pass, are elonf gated, as shown, to provide for-the angular movement of the stems when the finger piece is :depressed, and are also formed with lateral enlargements to permit passage of the stoppins- '5 The lateral enlargements in iithe slots in the stepped to a plate m and in the bo'ttomi plate kare, 0 course, in -corr,e-

' spending sides of" th'elslots, and the greater length of the slots in the bottom plate not only "permits --the' angular mevements of the "stems inthe operation of the machine, but

also allows manipulation of the stems in asfsembling. When the stems arerin position they occupy'jthe rear ends of the slots in the bottom plate dthe stop pins 7' are-in rear nlargements of such slots.
